LMV221SDX/NOPB

RF Detectors Overview

The LMV221SDX/NOPB is a logarithmic RF power detector manufactured by Texas Instruments, designed for cellular and wireless communication systems. It operates within an RF frequency range of 50 MHz to 3.5 GHz and provides a dynamic range of 40 dB. The device features a typical accuracy of ±0.5 dB across its operating range. It supports input power levels from -45 dBm to +5 dBm and functions with an operating supply voltage of 3.3 V. The component draws an operating supply current of 10 mA and is housed in a compact 6-pin WSON surface-mount package.

RF Detectors Procurement Notes

Verify the specific suffix NOPB confirms lead-free compliance and RoHS standards as per Texas Instruments documentation. Ensure the SDX variant matches the required tape-and-reel packaging configuration for automated assembly processes. Cross-reference the 6-WSON package dimensions against PCB footprint requirements to guarantee mechanical compatibility during integration.

RF Detectors Selection Notes

Select this component when a wide frequency coverage up to 3.5 GHz is required alongside precise logarithmic response characteristics. Consider the ±0.5 dB accuracy specification for applications demanding tight signal level tolerances. Evaluate the 10 mA supply current against system power budgets for battery-operated or energy-constrained wireless environments.

RF Detectors Part Context

This part belongs to the LMV221 family of logarithmic power detectors from Texas Instruments. The LMV221 series is engineered specifically for RF power measurement in modern wireless communication protocols. The SDX/NOPB designation indicates the surface-mount WSON package variant with lead-free manufacturing attributes.

RF Detectors Replacement Considerations

Consult official Texas Instruments substitution guides for direct pin-compatible alternatives. Verify that any substitute maintains the 50 MHz to 3.5 GHz frequency range and 40 dB dynamic range specifications.
